In a basic signaling sequence, which option represents a two-short-blast signal?

• A. Alternating course to starboard - international
• B. I intend to pass on starboard side - inland
• C. One short blast
• D. Two short blasts

Answer: (D)

Two short blasts are the exact sound pattern that represents a two-blast signal in basic vessel signaling. The number and type of blasts convey a specific maneuver, and this option is the one that literally matches the two-short-blast pattern described. The other options describe either a single short blast or a different instruction, so they don’t fit the two-short-blast signal. This pattern is part of how ships communicate intentions in close-quarters to avoid collisions.
